Transportation Worker Identification Credential (TWIC)
Maritime workers including terminal employees, longshoremen, truck drivers, agents and contractors must have a TWIC to gain unescorted access to Maryland Port Administration (MPA) facilities.
TWIC is federally mandated and enforcement is carried out by the U.S. Coast Guard. More Information regarding TWIC can be found on the Transportation Security Administration's (TSA) web site at https://www.tsa.gov/for-industry/twic . TSA recommends that all applicants enroll for TWIC (including renewals) a minimum of 60 days before applicants require a valid TWIC.
Although the MPA is not responsible for issuing the TWIC, there are some questions specific to the MPA facilities that are addressed here.
